A cylindrical copper rod of length 1.50 m and radius 2.00 cm is insulated to prevent heat loss

A cylindrical copper rod of length 1.50 m and radius 2.00 cm is insulated to prevent heat loss through its curved surface. One end is attached to a thermal reservoir fixed at 300°C; the other is attached to a thermal reservoir fixed at 30.0°C.What is the rate at which entropy increases for the rod-reservoirs system?
